Concert notes: Green Day in S.A.!

The first single is out. The new album is due in May. And the tour is scheduled to hit the AT&T Center Aug. 9.

Yes, Green Day will soon be back on the road, which is good news for S.A. rock fans in what has been a lean year for arena-level shows.

The punk rock heroes, who haven’t played S.A. since an August 2005 date at the SBC Center, hit the road in July in support of “21st Century Breakdown,” their first stduio album since 2004’s “American Idiot.” Produced by Butch Vig (Nirvana, Smashing Pumpkins, Garbage, Sonic Youth) and three years in the making, the album is due May 15. The first single, a bright, chunky, medium-tempo rocker called “Know Your Enemy,” came out last week.

The tour was announced by a publicist for the band’s record label, Reprise. There’s no ticket info yet.

In other concert news…one show that has confirmed is the Rockstar Energy Drink Mayhem Festival. Featuring Marilyn Manson, Slayer, Bullet For My Valentine and Killswitch Engage on the Main Stage, the show is happening Aug. 14 at the AT&T Center. Find ticket info and the rest of the lineup here.
